Contribution à l'analyse de la prise en compte du climat urbain dans les différents moyens d'intervention sur la ville

Abstract : Urbanization, with artificial surfaces replacing natural land, more anthropogenic heat and urban geometry, modifies the micro and meso scale climate. Such modifications do alter the radiative, thermal, moisture and aerodynamics properties of the urban environment. The study of energy balance could help understanding most of these changes. In this thesis, we used the urban surface exchange parameterization of Météo-France: Town Energy Balance, which computes water and energy exchanges between urban surfaces and atmosphere. In order to study the significance of different factors, we made a sensivity study. Factors are filed in five fields: building, public space, land use, industrial activities and transports. Our simulations showed that radiative parameters are the most influential during the summer. During winter, other thermal parameters (insulation) are the most influential. French local authorities could use several tools and means to act in favor of their climatic environment: their fields of direct jurisdiction (roads, parks, buildings which are owned by the community, etc.), guidance documents (SCOT and PLU), development procedures (urban development zone and building plotting), and incitement and pieces of information for their citizens and their agencies (local Agenda 21, Plan Climat, Approche Environnementale de l'Urbanisme). They can not work completely freely because of the boundary between urban planning law and building and dwelling law
